Two easy weeks. If it has done nothing, keep all of it and we refund you. Overnight kit, not for running in.

1. A technical sock is engineered to move moisture off skin

That is the whole spec. It is why you pay twenty pounds for one, and it does not switch off because you put balm on first.

2. So the honest contact time under merino is about twenty minutes

After that it is a sock with grease in it and a callus drying out again.

4. Nothing else in the routine changes

How it works

  2. Day Sock over it.
